Paper Abstract

This work focuses on numerical analysis of the possibility of the induction of the superstructure fiber Bragg gratings through applying of the pressing force. Namely, it is considered that a comb with given indent period is pressing on the fiber Bragg grating and as a result, due to the presence of the elasto-optic effect, local effective refractive index changes, leading to the change of the Bragg wavelength. In the presented numerical analysis it is assumed that incident light is polarized and either the whole energy of the signal is contained in the given linearly polarized mode or partially propagates in both linearly polarized modes. For the purposes of the presented analysis a Coupled Mode Theory (CMT) together with Transfer Matrix Method (TMM) and Jones Calculus has been employed.
